The Lowdown
Hey, it’s Rusty. Let’s cut to it: Kennebunk Beach is looking grim for the next couple of weeks. Water temp is about average for this time of year, around 63°, so that’s fine, but the waves are a no-show for most of it.
From now through Saturday the 19th, there’s nothing. Zero. The combined swell energy barely hits 50, with tiny surf and crap wind. A proper blank stretch.
The first real chance comes on Sunday, September 20th. We finally see some juice with a 6ft swell from the ENE, combined energy at 356 (moderate), and the wind goes glassy in the afternoon. That’s the standout. It’s a short-period windswell (7 seconds), but the clean, calm conditions make it the best option by a long shot. Kennebunk Beach is sheltered and needs that ENE direction, so it lines up. Expect some company, though—crowds are sometimes a thing here.
Monday the 21st has a leftover 4ft in the morning with clean offshore wind, but the energy drops to 172. It’s surfable but nothing special.
Then it’s another gap until Thursday the 24th, when the swell pumps up to 8ft with combined energy over 1200 (strong). That’s big and expert-only, plus the wind is cross-shore and choppy. Not a friendly wave. Probably better for kite surfing.
After that, the last few days are small and clean but not worth the paddle. Sunday the 27th and Monday the 28th have offshore wind but tiny waves and short periods.
So here’s the deal: Sunday the 20th afternoon is your one real shot. Everything else is a bust. Forecasts can change, but right now, that’s the truth.
Rusty out.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
